Evaluation of mandibular arch width change
The Journal of Prosthetic Dentistry, 1981The following conclusions can be drawn from this study and observations from the literature: The width of the mandible is influenced by intrinsic and extrinsic forces. Maximal opening, protrusion, and biting forces cause the mandible to decrease in arch width.

The effects of Fränkel II treatment on arch width and arch perimeter
American Journal of Orthodontics and Dentofacial Orthopedics, 1987Changes in dental arch width and total arch perimeter in 24 Class II, Division 1 patients treated with the Fränkel II appliance were compared with changes in an untreated control group. Measurements were made on pretreatment and posttreatment plaster casts at three points on each of four maxillary and four mandibular teeth.

Relationships between dental arch widths and widths of the face and head
American Journal of Orthodontics, 1951Abstract This paper treats three problems: the relationship between maxillary arch width and width of the upper face, the relationship between maxillary arch width and width of the head, and the relationship between mandibular arch width and width of the lower face. Original findings are reported on a sample of North American white children residing

A study of the literature reveals a variety of opinions on the potential for change in arch dimensions. The variations in sample sizes, treatment mechanics, and retention regimens may obscure relevant findings. These articles confirm some common findings, and a number of clinical cases are presented to illustrate these trends.

Sole Arch Width Extraction Using Greedy Algorithm
Proceedings of the 4th International Conference on Computer Science and Application Engineering, 2020In footwear production, the size of sole should be checked to match the corresponding upper before combining them. At present, manual recognition method and traditional machine vision method is not able to recognize unlabelled sole. In this paper, we propose a novel method to extract the feature parameter of unlabelled sole to recognize its size.

AbstractBackgroundThe visible maxillary arch width (VAW) is an important aesthetic‐determining feature. To date, there is no well‐established methodology to determine the aesthetically optimal VAW in customized treatment planning.MethodsIn this study, the common traits of the dentofacial configuration were investigated in most attractive Asian and ...

Deciduous dental arch widths and widths of the face in early childhood
American Journal of Orthodontics, 1951Abstract The data for this investigation were obtained from one hundred thirty white children (67 males, 63 females) who are enrolled in the Facial Growth Study being conducted at the University of Iowa. Approximately 95 per cent of the parents were of northwest European ancestry, and resided in or near Iowa City.

The phenomenon of decreased mandibular arch width in opening movements
The Journal of Prosthetic Dentistry, 1967Abstract Recent measurements indicate that deformation of the mandible occurs during opening movements. This important phenomenon is of considerable clinical significance. Further investigation, with a measuring apparatus rigidly attached to the teeth and possibly using strain gauges attached to fixed restorations, is indicated.

Arch width, canine position, and mandibular retention
American Journal of Orthodontics, 1973Abstract The canine-to-canine retainer technique has been used in the construction of an infinite number of such retainers. The chair time required is minimal, for the technique consists merely of making two canine bands and a plaster cast from a sectional compound impression.

Arch width after extraction and nonextraction treatment
American Journal of Orthodontics and Dentofacial Orthopedics, 2003An undocumented criticism of extraction treatment is that it results in narrower dental arches when compared with nonextraction therapy. Anterior and posterior arch widths of the maxillary and mandibular arches of 25 patients treated by 4 first-premolar extraction and 25 patients treated without extractions were measured on posttreatment study models ...
